CAASTRO, the ARC Centre of Excellence for All-sky Astrophysics, has welcomed this week’s announcement of two new Centres of Excellence that will build on its pioneering work: CAASTRO-3D (the ARC Centre of Excellence for All Sky Astrophysics in Three Dimensions),...

Star formation in galaxies is a local process whereby stars form out of molecular Hydrogen (H2). Detailed multiwavelength studies of the gas and stellar components of nearby galaxies have found the H2 star formation efficiency (SFEH2) – the ratio of star formation...

The era of very large all-sky radio surveys that probe down to very faint flux limits dawns upon us. Surveys such as the Evolutionary Map of the Universe (EMU), using the Australian Square Kilometre Array Pathfinder (ASKAP) telescope, will detect emission from many...

Our understanding of the environment within our nook of the Milky Way Galaxy is surprisingly limited. Astronomers generally look how the light from nearby background sources (stars, nebulae, etc.) is effected but there are very few nearby sources against which this...

Our view of the radio sky changes over time. This is partly because sources change over time: black holes devour stars and gas, stars go supernova, or clouds of fast moving electrons expand and slow. But variability is also partly due to our view through the cosmos:...
